And add one of these (or similar) for infinitely variable fan speed.

Not tried one myself but it should work. Been on my to do list for a while.

Worth a try for a fiver and it wouldn't take long to try it out if you can fish behind the dash to get to the switch wires. Make up some extension wires with Lucar's on the ends and you could be playing with it in under an hour.

All I need to do is but another S..... Hmmmm

A = 18"
B = 7"
C = 9"
D = 10"
E = 5" = fan motor sticks out another 2.25"
F = 2" dia.

Need any more?

whilst we are on the subject of the heater there is (imho) nothing wrong with the heater itself, it is capable of supplying ample heat, the issue is rather with the distribution system.

I have posted on this before but for anyone relatively new here this may (or quite possibly not) be useful/informative......

This photo shows the flap which moves to direct air either to the screen vents or, in the position shown, it blocks off the screen and air goes down the white tube to the footwell vents.
Perfect? Except that as you may be able to make out in the photo there is a whapping great gap at either end of the flap so the air, rather than try and find its way down a couple of metres of convoluted kinked and twisted vacuum cleaner hose says "no thanks, I'm going to take the easy route round the ends of the flap and out the screen vents"!

My solution was to fill those gaps with sticky back foam (draft excluder type stuff) and now, like it or not, majority of the air actually has no choice but to come out of the footwell eyeballs

[Jerseyjohn]

Thanks for info.

[Blue 30]

Really useful, thanks.
I'll bet you can't do that flap mod with the heater box in situ ?

Sounds like a useful mod/repair/upgrade.

Can you post a pic or two of your work ?

[tony 69]

Yeh I'll sort some out this weekend for you

Very interesting. I did a cross check and the same part fits several small Fiats! I wonder if it is the same as the Uno one I used!!

Isn't the Ka a Fiat 500 in disguise?

[tony 69]

I'm not sure I just looked on Ebay for something that looked close enough to mine and gave it a go. The KA is almost identical just got a slightly shorter shaft and a different mounting bracket, although the mount is far better.

Dont forget to post those pictures Tony! The more info we have the better and TVRees will be waiting to add any good info to his master list.
Couple of questions;

1. Were you able to use the Kia fan itself? It looks to be more sophisticated then the original TVR one. I had to fit the TVR one to the Uno motor which was a bit of a pain and meant the old fan was kept.

2. Hard for you to compare as your old one was dead, but they werent very effective, is the new fan powerful enough to give a decent demist air current? My Fiat one is better but still lacks demist power.

3. How is the Kia fan wired and what kind of switch is needed?

All information gratefully received!

[tony 69]

Ok I've taken what pics I can and hope they make sence to you..
The motor was from a ford KA and only has 2 wires and I will be using the switch off ebay so perfect


This is 1 of brackets that came with it and as you can see I've cut to lugs out from each corner. Then it was just a matter of doing the same to the other bracket then drilling too new holes in them and done.



Im hoping you can see but both brackets where clamped together and fastened on one side of the black plastic fastening on the fan box.
